Timor-Leste has some of the best dive sites in the world due to its location, warm waters, minimal tourist trade and lack of commercial fishing or heavy industry. Situated in the Coral Triangle, Timor is surrounded by deep water (about 2,500 m between Liquiçá and Alor Island, Indonesia) that gives home to an abundance of coral and fish life, including the annual migration of whales through the Ombai Strait and Wetar Strait according to a Marine Megafauna Survey in Timor Leste of June 2009. However, those same deep waters can cause strong currents at even the most protected sites so check the Tidal Predictions beforehand. High tide and days of smaller variation are usually better. Always have a good look at the water before entering.
While many of the dive sites can be reached by land, some of these entry points require a long walk over coral, a long surface swim or a boat.
